. To all whom it may concern I vunrrE STATES AT NT E CE l ABROM n. BRUNER, or rnr'mvroivr, ivrmivnso'rn. "Q 7 Be it known that I, ABRoM D."BRUN]sR, a citizen. of, the United Statespresidingat Fairmont, in [the county of Martin and State of Minnesota, have invented certain new and useful Improvements in Flows; and]; do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention has for its object to provide a plow with a movable mold board, especially adapted for use in a gumbo or like soil which, as is well known, will stick to a plow and not scour the same. 7

'To the above end, generally. stated, the

invention consists ofthe novel devices and combinations of devices hereinafter described and defined in the claims. 7

In the accompanying drawings, which illustrate the invention, like characters indicate, like parts throughout the. several views.

Referring to the drawings,

Figure l is an elevation of the land side of the improved plow, with a portion of the beam broken away;

Fig. 2 is a plan view of the improved plow with the beam sectioned on the line 00 m of Fig. 1;

Fig. 3 is an elevation of the field side of the improved plow, with some parts broken away and some parts shown in section;

Fig. 4 is a plan view of one of the sections of the mold board, on an enlarged scale;

Fig. 5 is a side elevation of the same;

Fig. 6 is a fragmentary detail view with some parts sectioned on the line m m of Fig. 3, on an enlarged scale;

Fig. 7 is a vertical section taken on the irregular line :20 m of Fig. 3, with some 1 parts removed Fig. 8. is a transverse section taken on the line 12 m of Fig. 7, on an enlarged scale; and

Fig. 9 is a fragmentary view of one of the sections of the mold board, on an enlarged scale, with the roller shown in section and illustrated in a difl'erentposition by means of broken lines.

The share, land side and beam of the improved plow are indicated, respectively, by the numerals 1, 2 and 3. Extending rearward and upward from the under side of the plow share 1, is a land side bracket 4 and a field side bracket 5, to which are countersunk thereln.

Preferably, ;as shown, the bracket 4 is tegrally formed with the land. side 1 of the plow and the bracket 5 is rigidly secured thereto by cross braces 7. These braces 7 Specification of Letters Patent. 2 I N 1918, Application filed 31111614, 1916. Serial No..1l)3,619.. r

are secured to the brackets 4 and 5 by nutequipped bolts 8, one of which extends through the plow beam 3 and rigidly con nects the upper end portion of the bracket 4 thereto. An oblique brace 9 rigidly supports the bracket 5 from the land side'2 of the plow. In the inner face of eachzbracket 4 and 5 is formed an endless runway '10 having at its upper extremity an entrance passage 11, normally closed by a removable section 12 held in-positionby a screw 13. 1

. The mold board for the plow is a movable apron-like structure made up of an endless series of slats 14, having beveledioverlap-T ping engagement at-their abutting longitudinal edges, Theend portions of these" slats 14 are mounted to slide on endless tracks 15 formed in the inner edge portions also held against endwise movements by endless. shoulders 16, also formed on the brackets 4 and 5. Each slat 14 is mounted on a carrier bar 17 and is detachably seof the brackets 4 and 5. These slats 14 are each carrier bar 17 is a pair of axially" alined trunnions 19, which project into the runways 10. The slats14 are preferably made from the same material, as the plow 7 share 1, so that they will scour under the action of the furrow moving thereover. On each trunnion 19, isa wabble' roller orwheel 20 connected thereto by a universal joint 21, arranged to travel in thev runway 10, in which the respective trunnion projects.

Sectional cover plates 22 are provided for the runways 10 to exclude therefrom dirt and dust. Each trunnion'l9carries one of the sections of the cover plates 22 and each of said sections is provided with a central aperture, through which the respective trunnion 19 projects. The cover plates, 22 are yieldingly pressed onto the brackets 4 and 5 to cover the runways 10 by coiled springs 23. One of these coiled springs 23 surrounds each trunnion'l9 and is compressed between the adjacent end of the carrying bar 17 and respective cover plate section 22. The lower extremities of the sections of the cover plates 22 are rounded to permit the same to make the turns at the true extremities of the runways 10.

The slats M are applied to or removed from the brackets t and 5 by inserting their rollersand trunnions through the passage ways 11. Of course, the removable sections 1:2 must be displaced to open the passageways 11. Cooperating with the movable mold board, is a scraper bar 24 which extends transversely thereof and its lower edge is held in proper relation to the mold board by nut-equipped bolts 25, having their heads countersunk therein and extended through vertically extended slots 26, formed in lugs 27 on the upper end portions of the brackets l and As best shown in Fig. 6, the scraper bar 2% is set oblique to the upper face of the mold board 1%, to remove there from any of the soil which may adhere thereto.

lVhen plowing, the furrow as the same is turned will fall upon the mold board I l and the frictional contact therewith will cause the upper inclined face thereof to travel upward in the direction of the arrow marked thereon in Fig. 3. This traveling movement of the mold board will discharge therefrom the furrow turned thereon, under the plowing action, and thus prevent the soil from sticking thereto. The wabble wheels 20 follow their irregular courses, during the traveling movement of the mold board, and permit independent endwise movements of the slats 14. In case one of the slats H is broken, or any of the parts associated therewith, the same can be very easily and quickly replaced by a new one.

What I claim is 1. A plow share having a mold board which is inclined longitudinally and laterally and consists of a pair of spaced brackets and an endless series of horizontal slats having their ends mounted on the brackets for movement longitudinally of the same.

2. A plow share having a mold board WfllCh' is inclined longitudinally and laterally and consists of a pair of spaced brackets, an endless series of longitudinal slats having their ends mounted on the brackets for movement longitudinally thereof, and means to cause the separation of the slats at the upper and lower extremities of the mold board.

In testimony whereof I aifix my signature in presence of two witnesses.
